Non-resonant coupled parallel resonant converter
Proceedings of the 32nd Midwest Symposium on Circuits and Systems, 2003A resonant converter using nonresonant coupling between the rectifier and resonant circuits is presented. This converter has many advantages over a conventional parallel resonant converter (PRC), such as better control characteristics, lower component stress, lower converter gain, and better stability.

LLC resonant converter with two resonant tanks
2010 Twenty-Fifth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2010To cope with the high power density and low cost in switching power supply, LLC resonant converters with the two resonant tank circuits composed of resonance capacitors and two transformers are proposed in this paper. Each transformers used for the proposed resonant circuits are parallel connected in the primary and series connected in the secondary to

Topologies for three-element resonant converters
IEEE Transactions on Power Electronics, 1990Many of the limitations of two-element resonant topologies can be overcome by adding a third reactive element. However, using three elements greatly increases the number of possible topologies, making it very difficult to explore this class of circuits on a trial-and-error basis. An orderly search procedure that exposes a large number of new topologies,

Resonant-tank control of parallel resonant converter
[Proceedings] Thirteenth International Telecommunications Energy Conference - INTELEC 91, 1993A control method, named resonant-tank control (RTC), is proposed for a parallel resonant power converter (PRC) operating above resonance. Using a simple linear combination of tank variables, it has potential for high-frequency DC-DC power converter applications.

A simple resonant frequency tracking technique for LLC resonant converters
2017 IEEE 6th International Conference on Renewable Energy Research and Applications (ICRERA), 2017A LLC resonant converter (LLC-RC) has been widely used in DC/DC converters for the benefits of high efficiency and high power density. The efficiency of a LLC resonant converter is greatly dependent on the switching frequency. In order to achieve higher efficiency, the switching frequency should be equal to the resonant frequency. This paper presents a

Analysis of Resonant Converters
1984The load parameter, Q, and the ratio of the switching frequency to the resonant frequency, Fs/Fo, characterize the operation of resonant converters. An accurate do analysis of the series and parallel resonant converters is given in terms of these parameters whereby the conversion ratio, peak stresses, and diode conduction time are determined.

Resonant converters with secondary-side resonance [PDF]
, 2016 A family of quasi-resonant converters is disclosed as comprising a voltage source, a transformer having primary and secondary windings, and a switch for periodically coupling the voltage source to the primary winding, whereby a charging current appears on the secondary winding. The transformer exhibits a characteristic leakage inductance.

Resonant switch converters are a broad class of converters in which the PWM switch network of a conventional buck, boost, or other converter is replaced with a switch cell containing resonant elements. These resonant elements are positioned such that one or more of the switching loss mechanisms is eliminated. The resulting hybrid converter combines the

Simulation of Resonant Converter Using Mathematical Model — A Case of Series Resonant Converter
2018 15th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON), 2018In this paper, how to do a simulation of resonant converter using mathematical model together with Euler Method will be described. Series resonant converter (SRC) operating in continuous conduction mode will be used as an example case. The simulation process will be shown step by step and followed by the simulation results.
